KSHB: Study Finds Diet and Exercise Reverse Brain's Aging

Getting more exercise and eating healthier are two of the most common New Year's resolutions, and a recent study shows sticking to those resolutions can benefit the brain as much as the body. 

The study, which was published in the journal Neurology, found non-strenuous exercise like walking or biking for 35 minutes three times a week for just six months could improve cognitive decline. Participants in the study who exercised and ate a healthy diet reversed their brain's aging by nine years. 

KSHB's Charlie Keegan spoke to Dr. Steven Arkin, a neurologist at Saint Luke's Marion Bloch Neuroscience Institute, about what the findings mean and how the study can apply to most people.
